Clustering analysis of CLE motifs in plants. The heat map shows the Euclidean distance of 2156 CLE motifs in 69 plant species. Red represents short distances. Blue represents long distances. A shorter Euclidean distance implies a higher degree of motif similarity. CLE motifs were clustered based on the Euclidean distance of each pair of sequences in a site-weight dependent manner. The clustering tree was generated using the HCL method. The information on the classification of the CLE motifs is shown on the top of the heatmap. All CLE motifs were clustered into six major groups: Group 1–5 and Group “others”. “TGD” and “Non-TGD” indicate whether the motif was from a potential tandem gene duplication (TGD). “Species” indicates that a motif was from a dicot, monocot or other type of plant species
